These tools also remember your login information and settings to make it easier and more efficient for you to use the Digital Platform or Marketing Site.

  • Right to Opt-Out of Targeted Advertising or Sharing (as applicable): Targeted advertising is the practice of serving you tailored advertisements based on your Personal Information gathered across other businesses, websites, applications, or services. Some jurisdictions may refer to this activity as “sharing.” As noted above, we do not engage in targeted advertising with respect to the Digital Platform.

Notice to California residents

We are required by the California Consumer Privacy Act of 2018, as amended (“CCPA”) to provide additional disclosures to California residents to explain how we collect, use, and disclose their Personal Information, and the rights and choices we offer California residents regarding our handling of their Personal Information.

In the past 12 months, we have collected the Personal Information described in “The Information We Collect” and disclosed it to third parties for the reasons identified in “The Information We Collect” and as listed in “Sharing Your Information.” The Personal Information listed in “The Information We Collect” may be categorized as follows under the CCPA:

  • Identifiers
  • Categories of Personal Information described in Cal. Civ. Code § 1798.80(e)
  • Characteristics of protected classifications under California or federal law
  • Commercial information
  • Internet or electronic network activity information
  • Geolocation data
  • Professional or employment-related information
  • Inferences drawn from certain demographic data
  • Sensitive Personal Information (health information that is not considered PHI, login credentials for your account with the Digital Platform, and the contents of messages that you send through the Marketing Site or Digital Platform)

We do not use or disclose Sensitive Personal Information for purposes other than those specified in Cal. Civ. Code § 1798.121.

We do not “sell” or “share” Personal Information collected through or on the Digital Platform.

Targeted advertising that we conduct on our Marketing Site (not the Digital Platform) may be considered a “sale” or “share” of Personal Information according to CCPA. Because we engage in this practice on the Site, we may have “sold” or “shared” identifiers, commercial information, and internet or electronic network activity information with third-party data analytics providers, social media networks, and marketing or advertising networks in the last 12 months. If you wish to request to opt out of this use of your information, please email with the subject line: Do Not Sell or Share My Personal Information. You may also submit this or other requests to exercise your rights under the CCPA by following the instructions in “How to Contact Us” listed above.

Transfer of data; special notice to non-U.S. users

Cylinder Health is a US-based provider, and our infrastructure – including databases and applications that handle and store Personal Information – is hosted in the US. As a result, it is necessary for us to transfer Personal Information within the United States to provide our services to users, pursuant to our relevant agreements with users and/or their employers or health plans.

If you believe that we have collected information from a child under the age of 18, please contact us through one of the methods listed under “How to Contact Us” above.
